Have a 2001 with the mach 460 sound system, and it somehow keeps drawing power from my battery and running my car dead because the alternator can't keep up. What can I do to stop it? And what would be the value drop if I put a different receiver in (custom)?

 

How do you know it's the 460?

 

What??

 

Fixed

 

Hey bone. How do I get that little corner speaker off the door? The one by the side view mirror. Can I pull it before the door panel is pulled?

 

Honestly I have never pulled mine. Ill get the diagram of of PTS and post it here on the forum so you can see it. Won't be able to till later. Currently not at my laptop

 

Cool man just wondering. It makes pulling the door panel difficult.

 

Because its the stock one that says "Mach 460" on the speakers and tweets

 

No! Really!!! I mean how do you know that is what is drawing power?...

 

Ohh sorry, I was trying to multi task.

I pulled the ground cable on my battery and put a check in between it and the ground post on my battery and a current was passing trough it with all accessories turned off and the key out of the ignition.
Then I had that connected still and started pulling fuses in my fuse box and I pulled out a fuse and the light went off. After some research online I found that it was the fuse for my instrument cluster. With the fuse pulled I then put the key in and turned it to the "on" position and see what would still work. The gauges worked still, a/c still worked, but the Mach 460 receiver and my shifter would NOT move.

 

Usually the 460 doesn't draw power. Unplug the radio itself and check the draw. Most likely its something else on that circuit.

 

Moving to sn95 forums.

is it possible that a switched accessory wire is grounding out somewhere and causing it to keep part of the 460 system on even with ignition off?

 

I'll give it a whirl and let you know what happens. But with it being my shifter and my stereo, wouldnt the problem be that obviously? I've never messed with a Mach 460 before this so I could very likely be wrong.

 

Yes. If a relay is hanging or something it is possible. Buy unusual. I'm betting its something else.

 

No, it's non functional with everything together and no key in the ignition. (if that's what you're asking)

 

I'll check it! I really want to keep original on the inside if at all possible w/o having to get a aftermarket receiver.

 

Yeah pull the head unit out and check your draw. There are more devices on that fuse.

 

The draw is coming from my receiver, and one of my amps in the trunk on the passenger side.

 

Weird.......

 

Yeah. That's after 2 hours of checking fuses and ground connections. So for now I just have them unplugged. I can't decided about fixing the stock receiver or just get a new aftermarket one.
